“…Since then, oxide-based LLP materials, especially aluminate-base and silicate-base luminescent host lattices which can be used for glass components, have attracted more and more attention and have been developed rapidly to replace the conventional long-lasting phosphorescent materials [9][10][11][12][13][14][15]. The brightness and persistent time of these new phosphors are more than 10 times longer than that of the previous sulfides, and remain visible well over 10 h after UV excitation.…”

“…The standby time thus limits the applicability of ML. On the other hand, there have been many experimental studies on the lifetime or transient processes of luminescence [11,12]. The lifetime is typically not affected by the excitation power or concentration of the sensor material.…”

The stress and loading rate on disks of SrAl2O4:Eu mixed epoxy resin were measured by a lifetime-based method. The concentration of the mechanoluminescence (ML) phosphor and the excitation power did not affect the measured lifetime. The lifetime was proportional to the stress and was inversely proportional to the loading rate. The concentration, the excitation power, the stress, and the loading rate affected the peak intensity of ML, while previous work estimated the stress using the absolute intensity under well-controlled excitation and concentration conditions. The method used here can shorten the measurement time and enhance the practicality of a ML phosphor.

“…In the past few years, phosphors activated with rare earth metals also have been investigated widely on account of their technological importance [2]. And strontium aluminates have been proved to be of good hosts for rare earth metals and rare earth metals doped strontium aluminates have been synthesized by different methods [2][3][4][5][6][7][8][9][10][11]. It is known that the Al/Sr ratio in the strontium aluminates phosphors can affect the long duration phosphorescence.…”

Sr 4 Al 2 O 7 :Eu 2? /Dy 3? phosphors are synthesized by the solid-state reaction. The obtained powders are characterized by XRD, SEM and luminescent spectrometer. The effects of the mole ratios of Dy 3? /Eu 2? on luminescent properties of Sr 4 Al 2 O 7 :Eu 2? /Dy 3? phosphors are investigated. The XRD pattern indicates that the powders have pure Sr 4 Al 2 O 7 phase. The SEM micrographs reveal that Sr 4 Al 2 O 7 :Eu 2? /Dy 3? phosphors show similar irregular morphology. Under the excitation of 360 nm, Sr 4 Al 2 O 7 :Eu 2? /Dy 3? phosphors exhibit the characteristic emission band originating from the 4f 6 5d 1 ? 4f 7 transition of Eu 2? ions. The emission intensity increases with the increasing mole ratio of Dy 3? /Eu 2? up to 3 and then decreases. Thermalluminescence results indicate that the persistent afterglow of Sr 4 Al 2 O 7 :Eu 2? /Dy 3? phosphors is generated by suitable electron traps formed by the Dy 3? ions within the host.
